Today to April 21 is the 31st National Cancer Prevention and Control Publicity Week. The latest data from the International Agency for Research on Cancer (IARC) under the World Health Organization (WHO) shows that lung cancer is currently the cancer with the highest incidence rate and mortality in the world, and it has ranked first in the global cancer mortality rate for ten consecutive years. Chen Keneng, director of the First Department of Thoracic Surgery of Peking University Cancer Hospital: According to the latest data released by the National Cancer Center, in 2022, the number of new cases of lung cancer in China will exceed 1.06 million, and the number of deaths will exceed 730000. Both the incidence rate and mortality rate will rank first in malignant tumors. From a global perspective, the incidence of lung cancer has continued to increase in the past 10 years, and the mortality rate has been ranked first for the past 10 years. This may be related to the current fast-paced lifestyle, improved industrialization level, increased stress, and the increasing number of smokers in developing countries. Early detection of lung cancer through asymptomatic CT scans is crucial. According to the latest statistics released by the International Agency for Research on Cancer, an average of 4 to 5 people are diagnosed with lung cancer every minute globally, and about 3 to 4 people die from the disease every minute. The International Agency for Research on Cancer calls for lung cancer to be preventable and have a high early cure rate, and the public should curb the surge of lung cancer at its source. The core of lung cancer prevention and treatment lies in "early detection, early diagnosis, and early treatment". Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: Clinically speaking, lung cancer with symptoms is generally not in the early stage, and more people in the early stage are actively screened. Experts say that early stage lung cancer is usually asymptomatic. Before 2012, China mainly screened through chest X-rays. In recent years, the popularization of low-dose spiral CT can increase the early detection rate of lung cancer to 90%. Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: For high-risk populations, we recommend regular CT screening once a year. In addition, experts emphasize that quitting smoking is the most effective measure to prevent lung cancer. Relevant data shows that after quitting smoking for 10 years, the risk of lung cancer can be reduced by more than 50%. Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: When can we achieve the same probability of developing lung cancer as non-smokers? Quit smoking for 15 years. Non high-risk populations do not need to undergo annual CT screening. Currently, China is promoting community CT screening for lung cancer, and some areas in Beijing have included lung cancer screening in chronic disease management, covering over one million people. Experts also emphasize that low-dose spiral CT has radiation, and non high-risk individuals do not need to undergo annual CT screening. Even if ground glass nodules are found in the lungs, do not be overly nervous and seek medical attention as needed. Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: For non high-risk populations, even if small nodules are seen on low-dose spiral CT, we should classify them into the following situations: if it is a pure ground glass nodule without solid components, do not panic excessively; If the nodule is not located beneath the pleura or in the interlobar fissure, there is no need to be nervous and there is no need to do a CT scan every year. Experts suggest that caution should be exercised when interpreting most of the ground glass nodules found during screening, as they grow very slowly and can be observed with a certain cooling off period. Overtreatment is not recommended. Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: It is unacceptable for people to confuse lung cancer with ground glass nodules with traditional lung cancer. The prognosis of ground glass nodules in lung cancer is not the same as that of traditional lung cancer. Simply put, it is a very lazy "lazy" cancer. With the advancement of medicine in our country, there have been significant breakthroughs in the treatment of lung cancer patients. For lung cancer with ground glass nodules, the 5-year survival rate is close to 100%, while for solid mass stage lung cancer, the 5-year survival rate is about 70% to 80%. At present, China not only brings hope to advanced lung cancer patients through breakthroughs in targeted drugs and immunotherapy, significantly prolonging their survival, but also tumor hospitals have made multidisciplinary collaboration (MDT) mode the core strategy for lung cancer diagnosis and treatment, further breaking through the bottleneck of efficacy. Chen Keneng, Director of the Department of Thoracic Surgery at Peking University Cancer Hospital: Our MDT (Multidisciplinary Collaboration) team is very strong, and someone has conducted retrospective research. Through MDT (Multidisciplinary Collaboration) discussions, locally advanced lung cancer patients can improve their 5-year survival rate by 5% to 10% compared to patients treated with a single specialty.
